Type error cannot read properties of undefined (reading InitalizeHeaderDrag)

[Christoph Weller]

Hello,

I have a blazor version dotnet core 8.0. Every time i navigate to a page with a sfgrid or a sfcard i get the above error. When i start the web debugger before i navigate to a page the error doesn't happen. Any idea ?

Best regards

Hi Christoph Weller,

Greetings from Syncfusion support.

Based on your query, we understand that you are encountering a TypeError when navigating to a page containing an SfGrid. To investigate this further, we created a sample application and attempted to reproduce the reported issue. However, in our testing, the SfGrid navigated between pages correctly without triggering any errors. Please refer to the attached sample for your reference.

Sample: Check the attachment.
Video demo: Check the attachment.

 

1. Could you share the complete Grid rendering code along with the model class? This will help us review your Grid configuration.
2. Provide a simple reproducible sample or try to reproduce the issue using our shared sample. This would help us validate and provide a better solution.
3.  Share us the video demonstration of the reported issue.
4. Please provide the NuGet version in which the issue is getting reproduced from your end.
